Usage Examples

Once connected, your AI assistant can:

Query incidents:

"Show me all P1 incidents assigned to the Network team"

Create a record:

"Create an incident for VPN outage affecting 50 users, P2, assign to Network Operations"

Aggregate data:

"How many incidents are there grouped by priority?"

Check health:

"Run a health check on our ServiceNow instance"

CMDB traversal:

"Show all upstream dependencies for the email-server-01 CI"

Schema introspection:

"What fields are on the change_request table?"

Code search:

"Find all business rules that reference GlideRecord('incident')"

ATF testing:

"Run ATF test suite abc123 and wait for results"

Safety Features

This server is designed for production use with multiple safety layers:

• Delete operations require explicit confirm: true
• Batch operations run in dry-run mode by default — shows match count without making changes
• Bulk deletes require both confirm and force flags
• Background scripts require confirm for destructive keywords (deleteRecord, deleteMultiple, etc.)
• Natural language writes require execute: true (reads execute immediately)
